This cam is not for the weak at heart. Intended for use as a MAX EFFORT NA style cam, we recommend using this in 427 and larger engines with a high compression ratio, heavily ported cylinder heads, and an aftermarket throttle body\/intake combo such as our Trinity series or CID style manifold. This camshaft @ 434\" CID and 14-1 compression ratio, AFR LS3 heads, and a CID intake with a vacuum pump on C12 fuel ran 5.50's @ 123.5 N\/A in the 1\/8 mile @ 2800 pds. Due to the aggressive nature and high valve lift of this camshaft, it is recommended for DRAG RACE USE ONLY!","brand":"Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":61757049667954,"sku":"BTR-427+MAXNA","price":459.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/hyper-motive-image-coming-soon_eb1ae2b6-dc4c-43e2-a977-3529d35cf3ee.png?v=1775962851","url":"https:\/\/hypermotive.com\/products\/btr-427-max-effort-na-camshaft","provider":"Hypermotive Performance","version":"1.0","type":"link"}
